   Integrated Control of Single-Phase Four-QuadrantLine-Side Converter and Machine-Side Inverter for Railway Traction Applications
By Carsten HEISING, Martin OETTMEIER, Volker STAUDT, Andreas STEIMEL [View]
[Download]

Abstract: A project is presented, in which four-quadrant converter, resonant tank and machine-side inverter of a railway traction vehicle operating at single-phase 16.7 Hz are treated as one unit, featuring an integrated model-based control of all quantities. The project aims at improving the dynamic behaviour of the overall system.

   Comparison of H-NPC and parallel-H topologies for AC Traction Front-End Converters

Abstract: In a context of limited switching frequency, as it is the case in railway traction applications, due to the relatively high transferred power and the necessity to limit power losses, two are the main solutions used for increasing input catenary current harmonic quality (and power): parallel association of several converters or using multilevel NPC topologies. In this paper these two AC traction front-end converter topologies are compared theoretically based on 3 different aspects: hardware requirements, modulation technique necessities and current harmonic quality. The study has been mainly focused in the third aspect, catenary current quality, which is considered as the most important. Consequently current quality has been analyzed in detail and validated in simulation and experimentally by means of various physical converter prototypes.

   A New On-board Energy Storage System for the Railway Rolling Stock Utilizing the Overvoltage Durability of Traction Motors
By MASAO YANO [View]
[Download]

Abstract: This paper proposes a new circuit configuration of an energy storage system, consisting of EDLC and its inverters connected in series to main motor windings and utilizing the overvoltage durability of traction motors. Our proposed system enables improved performance of the powering and the regenerative braking at the ever high speed region, without increasing traction motor current.
